This invention relates to track liners, and more particularly to a manually-operated track lining'jack having a high mechanical advantage.

' One object of the invention is to provide a device of the above nature which will be simple in construction, inexpensive to manufacture, easy to install and manipulate, compact, and very eificient and durable in use.

With these and'other objects in View there has been illustrated on the accompanying drawings one form in which the invention may be conveniently embodied in practice.

Fig. 1 represents a perspective view of the 5 improved track liner shown in operating position.

Fig. 2 is a transverse sectional View taken along the broken line 22 of Fig. 3.

Fig. 3 is a plan view of the track liner.

Fig. 4 is a side elevation of the same. 2

Referring now to the drawings in which like reference numerals denote corresponding parts throughout the several views, the numeral indicates a base, preferably rec- 25 tangular in shape, and having a pair of parallel upwardly projecting members 11 and 12, forming bearings for a horizontal shaft 13, upon which is keyed a ratchet wheel 14, the teeth of which are adapted to be engaged by the single tooth of a dog pawl 15 pivotally mounted on a pin 16 supported by said upstanding members 11 and 12. The ratchet wheel 14 is also adapted to be engaged by a multi-tooth pawl 17 pivotally mounted on a pin 18 on the end of a handle socket member 19 carrying a handle 20, said socket member 19 being pivoted on a horizontal shaft 21 supported by the upstanding members 11 and 12.

In order to push a rail 22 into alinement with other rails of a railway track supported on ties 28, and 23a, provision is made of a pusher arm 24 pivoted on a shaft 24a supported by enlarged bosses 24b and 240 located atthe front of the base 10. The pusher arm 24 has a pair of rearwardly-extending curved upwardly-inclined side tongues 25 and 26, said tongues being provided on their lower faces with pivotally mounted rollers 27, resting upon the upper surface of a pair of curved lifting members 28 and 28a, the latter being rigidly mounted upon the ratchet wheel shaft 13, as by keys 29.

The multi-tooth pawl 17 is provided with a plurality of teeth 30 on its lower edge, two of which teeth are adapted to engage the teeth of the ratchet wheel 14 at one time, as shown in Fig. 2. The upper end of the pawl 17 is provided with a manipulating finger 31 integral therewith for throwing said pawl out of action when, it is desired to lower the jack and remove the liner from the rail.

Operation In operation, when it is desired to aline a rail, the forward part of the device will first be inserted under the rail 22. The handle 20 will then be repeatedly raised and lowered as is usual with lifting jacks. Each time that the handle 20 is pushed down, the pawl 17 which engages the ratchet wheel 14-will be moved to the left, as viewed in Fig; 2, the teeth thereon causing'said ratchet wheel 14 to rotate in a counter-clockwise direction until the dog pawl 15 drops behind the next tooth on said ratchet wheel 14. The ratchet wheel 14 will be prevented from rotating backwardly or in a clockwise direction by said dog pawl 15.

.As the action is continued, the curved lifting arms 28 and 280' will be rotated step by step in a counter-clockwise direction, and by reason of the engagement of the lifting arms 28 and 28a with the rollers 27 in the rear ends of the tongues 25 and 26, the rail 22 will be pushed to the left, as shown in Fig. 1, into alinement with the adjacent rails.

7 When it is desired to remove the liner jack from under the; rail, the finger31 of the pawl 17 will be first raised by hand to bring the teeth 30 out of engagement with the teeth on the ratchet wheel 14, causing the side tooth 32 of said pawl to enter the notch 33 in the dog pawl 15. When the jack handle 2.0 is next pushed down, the tooth on the dog pawl 15 will be raised out of contact with thejratchct wheel 14 permitting said wheel to rotate in a clockwise direction until the pusher arm 24 has dropped sufiiciently to allow the jack to be pulled out from under the rail 22.

One advantage of this invention is that the track liner may be left in position under the rail while a train passes over it, it being merely necessary to remove the handle from its socket. I 1 While there has been disclosed in this specification one form in which the invention may i be embodied, it is to be understood that this form is shown for thepurpose of illustration only, and that the invention is not to be limited to the specificdisclosure but may be'modi- DOMENIOK TROCCHI.

theinvention includes all the modifications s and embodiments coming within the scope of the following claims.

q Havingthusfully described the invention,

what is claimed as new, and for which it i desired to secure LettersPatent, is i 1 I 1. In a railway track liner, a base,,a rail pusher arm pivoted at the front of said base,- said pusher arm having a pair of tongues at its rear end, roller 'bearingscarried by'each of said tongues, apair of pivoted curved rearwardly extending lifting arms engaging said rollers, and manually-operated means for rotating said liftingarms to raise said pusher arm. about its axis.

, 2; In a, railway track liner, a base, a rail pusher arm pivoted on said base and adapted to be located beneath a rail, said pusher arm having". a pair of rearwardly. extending tongues, a pairof rearwardly extending lifting arms located beneathisaid tongues, and manually operated means for rotating said liftingarms to raise said pusher armabout itsaxis'j I v 3. In a railway track liner, a base, a rail pusherarmpivoted onsaid base and adapted to be locatedbeneath a rail, said pusher arm having a pairgof rearwardlyextending tongues, a pair of rearwardly extending lifting armslooated beneath said tongues, and manually-operated means for rotatingv said lifting arms step by-step toraise said pusher arm about its axis.v p i a 4, In a railway track liner,,a base,l a rail pusher armjpi'voted on said base and adapted to be located under a rail, a lifting arm lo cated beneath the rear end of'said pusher arm, said lifting arm being non-rotatively carried by a shaft mounted to rotate insaid 1 base, a'ratchetwheel on said shaft, a man ually-operated pawl for rotating said ratchet Wheel in a direction to lift'said pusher arm,
